Joshua 7:2-5

2And Joshua sent men from Jericho to Ai, which is beside Beth-Aven, on the east side of Bethel, and spoke to them, saying, Go up and spy out the country. And the men went up and spied out Ai.

3And they returned to Joshua, and said to him, Let not all the people go up; let about two or three thousand men go up and smite Ai; make not all the people to toil thither, for they are few.

4And there went up thither of the people about three thousand men, but they fled before the men of Ai.

5And the men of Ai smote of them about thirty-six men; and they pursued them from before the gate to Shebarim, and smote them on the descent. Then the hearts of the people melted, and became as water.
